[0013] Before specifically describing the embodiments of the present disclosure, the knowledge that is the basis of the embodiments will be described. In recent years, by connecting devices to the Internet, information about the devices is displayed on a terminal device such as a smartphone. For example, if the device is equipped with a temperature sensor, temperature information is displayed on the terminal device. If the number of devices that can be connected to such a network increases, multiple devices may be installed in one space. Under such circumstances, if information acquired from the devices is displayed for each device on the terminal device, the user must check and estimate the information about the multiple devices in order to understand the temperature of the space. Therefore, it is required to present the information about the space that the user needs in a more understandable manner by collecting, calculating, and displaying information about the devices on a space-by-space basis.

[0014] 1(a)-(c) show the configuration of a notification system 1000. The notification system 1000 includes an air purifier 100, a ventilation fan 110, an air conditioner 120, a router 200, a network 300, a server 400, a terminal device 500, and a smart speaker 600. The air purifier 100, the ventilation fan 110, and the air conditioner 120 are collectively referred to as devices.

[0015] The air purifier 100 is a device having a removal function for removing dust, pollen, house dust, and the like suspended in the air. The air purifier 100 is equipped with, for example, a thermometer for measuring temperature, a hygrometer for measuring humidity, a particulate matter sensor for measuring the density of particulate matter such as PM2.5, a gas sensor for measuring the density of gas, and a dust sensor for measuring the density of dust. The thermometer, hygrometer, particulate matter sensor, gas sensor, and dust sensor are collectively referred to as sensors.

[0016] The exhaust fan 110 is a fan for exhausting indoor air and smoke, or for replacing the indoor air with outdoor air (ventilation). The ventilation fan 110 is a device that is forcibly executed by an application. The ventilation fan 110 is equipped with, for example, a thermometer for measuring temperature, a hygrometer for measuring humidity, and a CO2 sensor for measuring the density of CO2. The thermometer, hygrometer, and CO2 sensor are also collectively referred to as sensors. The air conditioner 120 is one type of air conditioning equipment, and is a device that adjusts the temperature and humidity of the air in the room. The air conditioner 120 is equipped with, for example, a thermometer for measuring temperature, and a hygrometer for measuring humidity. The thermometer and hygrometer are also collectively referred to as sensors. In this way, different types of sensors are installed for each device.

[0017] The air purifier 100, the ventilator fan 110, and the air conditioner 120 have a communication function for wireless or wired communication, and can communicate with a router 200 installed in the facility in which they are installed. The router 200 communicates with a terminal device 500 and a smart speaker 600 in the facility, and also communicates with a network 300 outside the facility. The network 300 is, for example, the Internet, and is configured by wired communication, wireless communication, or a combination thereof. A server 400 is connected to the network 300.

[0018] With this configuration, the detection results of the sensors of the air purifier 100, the ventilation fan 110, and the air conditioner 120 can be confirmed on the terminal device 500 or the smart speaker 600. The terminal device 500 or the smart speaker 600 transmits a signal for requesting transmission of the detection results (hereinafter referred to as a "request signal") to the server 400 via the router 200 and the network 300. The server 400 transmits the request signal to the air purifier 100, the ventilation fan 110, and the air conditioner 120 via the network 300 and the router 200. The air purifier 100, the ventilation fan 110, and the air conditioner 120 transmit the detection results to the server 400 via the router 200 and the network 300. The server 400 transmits the detection results to the terminal device 500 and the smart speaker 600 via the network 300 and the router 200. The terminal device 500 and the smart speaker 600 display the detection results or output them as sound.

[0019] If the sensor detection results are output as is in the terminal device 500 and the smart speaker 600, it is difficult for the user to understand. Therefore, the server 400 executes processing on the detection results and transmits the processing results to the terminal device 500 and the smart speaker 600 via the network 300 and the router 200. The terminal device 500 and the smart speaker 600 display the processing results or output audio. Such processing will be described in detail below.

[0020] FIG. 2 shows the configuration of a room in which the notification system 1000 is installed. The facility is, for example, a house, and includes a plurality of rooms. Each of the plurality of rooms includes, for example, a living room 700, a bedroom 710, a dining room 720, and a Japanese-style room 730. The living room 700, the bedroom 710, the dining room 720, and the Japanese-style room 730 can be said to be a single space independent of each other. The living room 700 is installed with a first air purifier 100a and a second air purifier 100b, and the bedroom 710 is installed with a third air purifier 100c, a first ventilation fan 110a, and an air conditioner 120. The dining room 720 is installed with a fourth air purifier 100d, and the Japanese-style room 730 is installed with a fifth air purifier 100e and a second ventilation fan 110b. The first air purifier 100a, the second air purifier 100b, the third air purifier 100c, the fourth air purifier 100d, and the fifth air purifier 100e are collectively referred to as air purifier 100, and the first ventilation fan 110a and the second ventilation fan 110b are collectively referred to as ventilation fan 110. Here, a plurality of devices equipped with the same sensor are installed in the living room 700, and a plurality of devices equipped with different sensors are installed in the bedroom 710 and the Japanese-style room 730.

[0021] 3(a)-(c) show information in the notification system 1000. FIG. 3(a) shows information in the first air purifier 100a and the second air purifier 100b installed in the living room 700 of FIG. 3 shows the detection results in the first air purifier 100a. The temperature and humidity values ​​detected in the first air purifier 100a are shown as they are. In addition, the gas detection value, small dust detection value, large dust detection value, and PM2.5 detection value in the first air purifier 100a are each shown as a six-stage dirt level from 0 to 5. For example, the dirt level approaches "5" as the detection value increases. For such a six-stage evaluation, multiple threshold values ​​are preset in the first air purifier 100a, and the detected value is compared with the multiple threshold values. Furthermore, the pollen detection value in the first air purifier 100a is shown as a two-stage dirt level from 0 to 1. The dirt level "0" indicates that no pollen is detected, and the dirt level "1" indicates that pollen is detected. The same applies to the second air purifier 100b. Figures 3(b)-(c) will be described later.

[0022] 4(a)-(b) show the configuration of the server 400 and the terminal device 500. The server 400 in FIG. 4(a) includes a communication unit 410, a control unit 420, and a storage unit 430. As described above, the detection results of each of the multiple devices are transmitted to the server 400 via the router 200 and the network 300. Each of the multiple devices is, for example, the air purifier 100, the ventilation fan 110, and the air conditioner 120 in FIG. 1 and FIG. 2. Here, each detection result includes identification information "ID" for identifying the device that is the transmission source. The communication unit 410 receives the detection result. The communication unit 410 outputs the received detection result to the control unit 420. Therefore, it can be said that the control unit 420 acquires the detection result of each of the multiple devices from each of the multiple devices. The control unit 420 stores the detection result in the storage unit 430 based on the ID included in the detection result.

[0023] The storage unit 430 stores the detection results for each ID. The storage unit 430 also stores the correspondence between the ID and the identification information of the space in which the device with the ID is installed (hereinafter referred to as "space ID"). For example, the living room 700 in FIG. 2 is assigned the space ID "1", the bedroom 710 is assigned the space ID "2", the dining room 720 is assigned the space ID "3", and the Japanese-style room 730 is assigned the space ID "4". Based on the correspondence stored in the storage unit 430, the control unit 420 organizes the detection results of each device stored in the storage unit 430 as detection results for each space ID. This corresponds to organizing the detection results of each device into detection results for each room, that is, for each same space.

[0024] For example, the detection results for the space ID "1" are the detection results of the sensors mounted on the first air purifier 100a and the second air purifier 100b arranged in the living room 700. Therefore, these detection results are the detection values ​​of temperature, humidity, gas, dust (small, large), particulate matter (PM2.5), and pollen. That is, the values ​​of multiple types of components are acquired. The control unit 420 derives air quality information that is an aggregation of the detection results from two or more devices arranged in the same space and that includes the values ​​of multiple types of components. To be more specific, the control unit 420 performs statistical processing for each component on the detection results from two or more devices arranged in the same space. Here, the air quality information is a collective term for information on temperature, humidity, gas, dust (small, large), particulate matter (PM2.5), pollen, and the like in the air.

[0025] When the temperature in the first air purifier 100a indicates 22°C and the temperature in the second air purifier 100b indicates 24°C, the control unit 420 averages these temperatures to derive a temperature of "23°C" in the living room 700. The control unit 420 also performs averaging processing on the humidity in the same manner as for the temperature. The control unit 420 also compares the gas detection value in the first air purifier 100a with the gas detection value in the second air purifier 100b to select the maximum value. For example, when the gas detection value in the first air purifier 100a indicates a dirt level of "1" and the gas detection value in the second air purifier 100b indicates a dirt level of "3", the gas detection value in the living room 700 is determined to be the dirt level of "3". The control unit 420 calculates the detection value of dust (small and large), particulate matter, etc. The same processing as for the gas detection values ​​is also performed on the (PM2.5) detection values ​​and the pollen detection values. Here, control unit 420 may use any of the minimum, maximum, and average values ​​for each component. Such processing is shown in FIG. 3(b). As a result, control unit 420 generates information on the air quality in living room 700, which includes multiple types of components such as temperature, humidity, gas detection values, dust (small and large) detection values, particulate matter (PM2.5) detection values, and pollen detection values.

[0026] Moreover, the detection results for the space ID "2" are the detection results of the sensors mounted on the third air purifier 100c, the first ventilation fan 110a, and the air conditioner 120 arranged in the bedroom 710. Therefore, these detection results are the temperature, humidity, gas detection values, dust (small, large) detection values, particulate matter (PM2.5) detection values, pollen detection values, and CO2 detection values. Here, the CO2 detection value is output only from the first ventilation fan 110a, and the gas detection value, dust (small, large) detection value, particulate matter (PM2.5) detection value, and pollen detection value are output only from the third air purifier 100c. Therefore, the control unit 420 regards the CO2 detection value from the first ventilation fan 110a as the CO2 detection value in the bedroom 710. Furthermore, control unit 420 regards the gas detection values, dust detection values ​​(small and large), particulate matter (PM2.5), and pollen detection values ​​from third air purifier 100c as those detection values ​​in bedroom 710. The same processing as that in living room 700 is performed for temperature and humidity. As a result, control unit 420 generates information on the air quality in bedroom 710, which includes multiple types of components such as temperature, humidity, gas detection values, dust detection values ​​(small and large), particulate matter (PM2.5), pollen detection values, and CO2 detection values.

[0027] The control unit 420 executes similar processing for the dining room 720 with space ID “3” and the Japanese-style room 730 with space ID “4.” The communication unit 410 transmits the air quality information for each space to the terminal device 500 via the network 300 and the router 200.

[0028] Terminal device 500 in Fig. 4(b) includes communication unit 510, control unit 520, display unit 530, and operation unit 540. Communication unit 510 receives air quality information from server 400. Communication unit 510 outputs the air quality information to control unit 520. Therefore, it can be said that control unit 520 acquires air quality information from server 400, the air quality information including values ​​of multiple types of components and summarizing the detection results of multiple devices arranged in the same space. In particular, the values ​​of the multiple types of components included in the air quality information are two or more of temperature, humidity, gas detection values, dust (small and large) detection values, particulate matter (PM2.5) detection values, pollen detection values, and CO2 detection values.

[0029] The control unit 520 derives an index indicating the air quality in a space based on the values ​​of multiple types of components included in the information on the air quality in the space. Figures 5(a)-(c) show an overview of the processing in the control unit 520. Figure 5(a) shows the data structure of a table used to derive an index. The vertical axis shows the dirt level for the gas detection value, and the horizontal axis shows the dirt level for the dust (small and large) detection value, the particulate matter (PM2.5) detection value, and the pollen detection value. When the dirt level on the vertical axis is "0" and the dirt level on the horizontal axis is "0", an index with a first color ring surrounding the message "Clean" is associated. When the dirt level on the vertical axis is "1" and the dirt level on the horizontal axis is "0", or when the dirt level on the vertical axis is "2" and the dirt level on the horizontal axis is "0" or "1", an index with a second color ring surrounding the message "Smell" is associated. If the dirt level on the horizontal axis is "1" and the dirt level on the vertical axis is either "0" or "1", or if the dirt level on the horizontal axis is "2" and the dirt level on the vertical axis is anything between "0" and "2", an indicator with the message "dusty" surrounded by a ring of a second color is associated.

[0030] When the dirt level on the vertical axis is "3" and the dirt level on the horizontal axis is any one of "0" to "2", or when the dirt level on the vertical axis is "4" and the dirt level on the horizontal axis is any one of "0" to "3", or when the dirt level on the vertical axis is "5" and the dirt level on the horizontal axis is any one of "0" to "4", an index with a third color ring surrounding the message "smelly" is associated. When the dirt level on the horizontal axis is "3" and the dirt level on the vertical axis is either "0" or "3", or when the dirt level on the horizontal axis is "4" and the dirt level on the vertical axis is any one of "0" to "4", or when the dirt level on the horizontal axis is "5" and the dirt level on the vertical axis is any one of "0" to "5", an index with a third color ring surrounding the message "dusty" is associated. Here, the first color, the second color, and the third color are different from each other. For example, the first color is green, the second color is yellow, and the third color is red. The first, second, and third colors may be defined by differences in density. For example, the first color is displayed as the lightest and the third color is displayed as the darkest.

[0031] Control unit 520 associates the detection values ​​of gases included in the air quality information with the vertical axis. Control unit 520 also selects the maximum value among the detection values ​​of dust (small, large), particulate matter (PM2.5), and pollen included in the air quality information. Control unit 520 further associates the maximum value with the horizontal axis. In this way, control unit 520 obtains a single index that encloses a message in a ring. In other words, control unit 520 derives a single index based on the relationship between one of the detection values ​​of dust (small, large), particulate matter (PM2.5), and pollen and the detection value of gas.

[0032] Furthermore, control unit 520 classifies the multiple types of components included in the air quality information into three icon display sensor groups as shown in Fig. 5(b). Control unit 520 classifies the detection values ​​of dust (small, large), particulate matter (PM2.5), and pollen into the icon display sensor group "house dust / pollen", the detection values ​​of particulate matter (PM2.5) into the icon display sensor group "PM2.5", and the detection values ​​of gas into the icon display sensor group "odor".

[0033] The control unit 520 selects the maximum dirt level among the detection values ​​of dust (small, large), particulate matter (PM2.5), and pollen in the icon display sensor group "house dust / pollen". The control unit 520 specifies the number of icons from the selected maximum dirt level based on the relationship shown in FIG. 5(c). The control unit 520 also specifies the number of icons from the detection value of particulate matter (PM2.5) in the icon display sensor group "PM2.5" based on the relationship shown in FIG. 5(c). Furthermore, the control unit 520 specifies the number of icons from the detection value of gas in the icon display sensor group "odor" based on the relationship shown in FIG. The result of such processing is shown as in FIG. 3(c).

[0034] The control unit 520 generates a screen based on one derived index and the number of icons in the icon display sensor group, and displays the screen on the display unit 530. FIGS. 6(a)-(c) show screens displayed on the display unit 530. As shown in FIG. 6(a), the name of the room is displayed in a space display field 800. Here, it is assumed that the space is the living room 700. A temperature and humidity display field 810 is disposed below the space display field 800. The temperature and humidity display field 810 shows the temperature and humidity in the living room 700. An index 820 derived in the control unit 520 is displayed below the temperature and humidity display field 810.

[0035] Furthermore, at the bottom of the screen, an odor group 830, a PM2.5 group 840, and a house dust / pollen group 850 are arranged horizontally. In the odor group 830, the number of icons specified for the icon display sensor group "Odor" is displayed. In the PM2.5 group 840, the number of icons specified for the icon display sensor group "PM2.5" is displayed. A number of icons are displayed. In the house dust / pollen group 850, a number of icons specified for the icon display sensor group "house dust / pollen" are displayed. Figures 6(b)-(c) show screens for a different space from that shown in Figure 6(a). This is shown in the same way as Figure 6(a), so a description thereof will be omitted here.

[0036] The operation unit 540 is an interface that accepts user operations. The operation unit 540 is, for example, a touch panel or a button. When the operation unit 540 is a touch panel, the display unit 530 and the operation unit 540 are integrally configured. The smart speaker 600 in FIG. 1 executes the same process as the terminal device 500, and therefore a description thereof will be omitted here. In this case, the smart speaker 600 outputs audio instead of displaying on the terminal device 500.

[0037] The notification system 1000 in FIG. 1(b) includes a first base station device 310a and a second base station device 310b, which are collectively referred to as the base station device 310, in comparison with FIG. 1(a). A SIM (Subscriber Identity Module) card 320 can be inserted into the air purifier 100. The air purifier 100 connects to the first base station device 310a and communicates with the server 400 via the network 300. The terminal device 500 connects to the second base station device 310b and connects to the server 400 via the network 300. That is, the air purifier 100 and the terminal device 500 connect to the server 400 without going through the router 200. The notification system 1000 in FIG. 1(c) does not include the network 300 and the server 400 in comparison with FIG. 1(a). Therefore, the processing in the server 400 so far is executed in the terminal device 500 or the smart speaker 600.

[0038] The subject of the device, system, or method in the present disclosure includes a computer. The computer executes a program to realize the function of the subject of the device, system, or method in the present disclosure. The computer includes a processor that operates according to a program as a main hardware configuration. The type of the processor does not matter as long as it can realize the function by executing the program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). The multiple electronic circuits may be integrated into one chip or may be provided on multiple chips. The multiple chips may be integrated into one device or may be provided on multiple devices. The program is recorded on a non-transitory recording medium such as a computer-readable ROM, an optical disk, or a hard disk drive. The program may be stored in the recording medium in advance, or may be supplied to the recording medium via a wide area communication network including the Internet.

[0039] The operation of the notification system 1000 configured as above will be described. FIG. 7 is a sequence diagram showing a display procedure by the notification system 1000. The terminal device 500 transmits a request signal to the server 400 (S10). The server 400 transmits a request signal to the first air purifier 100a (S12) and also transmits a request signal to the second air purifier 100b (S14). The first air purifier 100a transmits the detection result to the server 400 (S16), and the second air purifier 100b transmits the detection result to the server 400 (S18). The server 400 derives air quality information that summarizes the detection results for each room (S20). The server 400 transmits the air quality information to the terminal device 500 (S22). The terminal device 500 derives an index based on the air quality information (S24), and displays a screen including the index on the display unit 530 (S26).

[0040] According to this embodiment, a single index showing the air quality in a single space is displayed on the screen based on the values ​​of multiple types of components contained in the air quality information that is a compilation of the detection results of multiple devices arranged in the same space, so that the air quality in a single space can be notified. In addition, since the air quality in a single space is notified, the user can instantly grasp the information about the space. In addition, the values ​​of multiple types of components included in the air quality information are two or more of the detection values ​​of gas, dust, particulate matter, and pollen, so that the details of the air quality can be grasped. In addition, one index is derived based on the relationship between the detection value of gas and one of the detection values ​​of dust, particulate matter, and pollen, so that the air quality in one space can be easily notified.

[0041] In addition, the system derives air quality information that is a compilation of detection results from two or more devices among multiple devices that are located in the same space, and that includes values ​​of multiple types of components, making it possible to inform the air quality in one space.In addition, the system derives air quality information by performing statistical processing for each component on the detection results from two or more devices located in the same space, making it possible to improve the accuracy of the derived air quality.In addition, the system selects the maximum value as the statistical processing, making it possible to inform the worst air quality.

[0042] An overview of one aspect of the present disclosure is as follows: A program according to one aspect of the present disclosure causes a computer to execute the steps of externally acquiring air quality information including values ​​of multiple types of components and summarizing detection results of multiple devices arranged in the same space, deriving an index showing the air quality in the same space based on the values ​​of the multiple types of components included in the acquired air quality information, and displaying the derived index on a screen.

[0043] The values ​​of multiple types of components included in the air quality information acquired in the acquiring step may be two or more of gas detection values, dust detection values, particulate matter detection values, and pollen detection values.

[0044] The values ​​of multiple types of components included in the air quality information acquired in the acquiring step may include a gas detection value, and the deriving step may derive an index based on the relationship between one of the dust detection value, the particulate matter detection value, and the pollen detection value and the gas detection value.

[0045] Computers that execute the programs described herein are also within the scope of the present disclosure.

[0046] Another aspect of the present disclosure is also a program that causes a computer to execute the steps of acquiring detection results from each of a plurality of devices, deriving air quality information that is an aggregation of detection results from two or more devices among the plurality of devices that are arranged in the same space and that includes values ​​of a plurality of types of components, and outputting the derived air quality information.

[0047] The deriving step may derive the air quality information by performing statistical processing for each component on detection results from two or more devices arranged in the same space.

[0048] The deriving step may select a maximum value as the statistical process.

[0049] The values ​​of the multiple types of components included in the air quality information derived in the deriving step may be two or more of a gas detection value, a dust detection value, a particulate matter detection value, and a pollen detection value.
